Condensing boilersThe classic system for generating heat, the condensing boiler is a highly sophisticatedsolution. JUMO have years of experience in this area and as a result, can provideall the necessary measurement and control system products to perfectly equip thistype of system. JUMO has been a reliable partner to the heating industry for manyyears. Whether in the context of joint development at the start of a product phase,or when adapting products during their lifecycle, JUMO is always anxious to beinvolved in developing the best-possible solution for safe condensing boiler control.

Monitoring the process water temperatureThe strict standards of hygiene that have to be met for thestorage of the process water require precise regulation ofthe water temperature in the storage media. The 60°C maximum process water temperature must not be excee-ded, nor must the temperature fall below 55°C. Resistance thermometers from JUMO provide safe and reliable solutions for monitoring the temperature of the process water. Of course, these solutions can also be trans-ferred to all areas of temperature measurement in heatinginstallations.

Condensing boilers

Operating principleCondensing boiler technology is based on burning fossilenergy sources, such as oil or gas. The energy source isbrought into the combustion chamber of the boiler plant,where it burns and releases heat energy and exhaust gases.The released heat energy is delivered through the water thatpasses the combustion chamber in pipes. This water has al-ready been pre-heated in a condensation heat exchanger,using the heat energy from the exhaust gases. This makesoptimum use of fuel source.

Solid fuel boilersHeating with solid fuels inevitably involves the highest temperature produced byan open flame. It is particularly important here that all protection systems arereliable and made to last. JUMO provides you with exactly the right solutions:safe – reliable – advanced. With a finger permanently on the pulse of the technologyyou need to protect your boiler plants.

Solid fuel boilers

Operating principleA solid fuel boiler can be fired with all solid fuels, which ofcourse also includes firewood. The air needed for the com-bustion process is provided by the natural draft method. Thefuel is placed onto a grate and burns up or down, dependingon the type of system involved. The heat energy produced inthis way is delivered to the heating system water by a heatexchanger.

Monitoring the exhaust gas temperature in bivalent operationA frequently seen method of operation with solid fuel boilersis bivalent operation with a condensing boiler. An exhaustgas temperature monitor (ATW) must be deployed to ensurethat only one of the systems is used to generate energy. TheATW measures the temperature in the exhaust pipe of thesolid fuel boiler. When the temperature reaches 80°C, theATW automatically disables the condenser boiler. The JUMOheatTHERM-AT is the optimum design for new types of boiler.

Pellet heating systemMeasurement and control systems are a necessary part of any heating system,and this includes pellet heating systems. The choice and size of this heating system is always heavily dependent on customer requirements and on the physical on-site conditions. This means that it is particularly important to have a reliable measurement and control system partner, who can be flexible aboutcustomizing the systems solutions that they provide. JUMO is always anxiousthat you implement the optimum solution for your project.

Pellet heating system

Operating principleWith larger pellet heating systems, the fuel, the wood pellets,are fed to the boiler burner by a screw or suction conveyor. Thecombustion process is ignited electrically, and burns the con-tinuous supply of pellets. The heat energy produced in this wayis delivered to the heating system water. The exhaust gases thatare produced rise up and run through a heat exchanger system. There, the heat that they contain is delivered to theheating system water before the now cooled exhaust gasesare directed out into the atmosphere via the chimney.

Temperature visualizationThe greater the heat output from a pellet heating system,the more important it is to have constant control over thetemperatures actually present in the process. The JUMOdi308 digital indicator allows you to read the current processtemperature at any time. Because you can program the minimum and maximum values, you can also safely control your process. An additionalaid when monitoring is the alarm text’s change of color fromred to green, or vice versa, which visually assists your processcontrol.

Combined heat and power plantWith this innovative heat generation concept, you also produce, quite incidentally,enough power for everyday use. Because a combined heat and power plant is sohighly complex, it is particularly important for all the components to be perfectlyadapted to one another. By using measurement and control systems from JUMO,you make sure that all the components are always operating in the correct tem-perature range. You can then relax and enjoy the benefits of cogeneration.

Combined heat and power plant

Operating principleIn the combined heat and power plant (CHP plant), a combus-tion engine designed for gas or diesel operation drives a gene-rator. This converts the mechanical energy produced by theengine into electrical energy. The combustion engine is protected against overheating by cooling water. The coolingprocess heats the water in the cooling circuit to approx. 80 to90°C. To cool it down, it is directed through a heat exchanger,where the excess heat energy is delivered to a heating circuit.The heating water, that has already been pre-heated to approx.70°C, then passes through a exhaust gas heat exchanger. Thereit absorbs some of the exhaust gas heat from running the en-gine, which brings it to its final use temperature of 90 to 100°C.

Monitoring pressure and temperature in the cooling circuit of a combustion engineThe safe and reliable operation of a combustion engine is essentially decided by engine lubrication and cooling. The important parameters here are pressure and temperature.Optimum control of the oil pressure and temperature, forexample, prevents bearing damage. In the cooling circuit, onthe other hand, a slight overpressure helps to shift the coolantboiling point to 115°C.Here too, the temperature as well as thepressure must be monitored. The thermostat does not needany auxiliary power to monitor the critical temperature valuesand in an emergency, switch off the CHP plant.

Air conditioner/heat pumpIn an automatic home ventilation system, air conditioners provide optimum air conditionsin modern buildings. Because these devices are split into an outdoor and an indoorunit, they make different demands on measurement and control systems. JUMO controllers have no difficulty in meeting the challenge. The JUMO product portfoliofor the various areas of measurement and control technology has so many variations,you will always be able to find the solution you require.

Air conditioner/heat pumpOperating principleAir conditioners work according to the Carnot principle. Theyalways consist of at least two units, an outdoor unit and an indoor unit. Refrigerant continuously circulates between thetwo units. In the indoor unit, this is heated by the room heat,and evaporates. If the refrigerant, in the form of vapor, nowencounters an ambient temperature lower than its own tem-perature in the outdoor unit, it gives off heat to the outdoorunit and in so doing, returns to the liquid state. It is then pum-ped back to the indoor unit, where it can once again take up the heat in the home. The advantage for devices that operate under this principle is that in the in-between seasons

(outdoor temperatures between 5 and 15°C), they also act asa heat pump, thus helping to reduce heating costs.

Frost protection of the outdoor unit Protecting the outdoor unit of an air conditioner against frostdamage is a very important task that can be discharged bythe JUMO frostTHERM-AT. Because the capillary tubing followsa winding course across the outdoor unit, the thermostat al-ready responds from a 30cm “frost section”. If the presettemperature on a section like this is reached, the thermostatconnects the required heat unit, or switches off the system.Moisture condensation and frost damage are avoided.
